The trick is to "feed" the entire range to UNIQUE so that it finds the unique combinations of values in multiple columns. After that, you simply enclose the formula in the ROWS function to calculate the number of rows. For example, to count the unique rows in the range A2:C10, we use...
in general, is very large. For the analysis of 3D representations of plants in particular, a diverse set of tools is required because of the complexity and the non-solid characteristics of plant architecture, and its diversity both across and within species. It is our goal to point out...

The formula to calculate the Aitchison distance between two generic vectors x and y of length m is: dA x, y = 1 m−1 m ln xi − ln yi 2 m i=1 j=i+1 xj yj (9) As for SMAPE, we computed Aitchison distance on CPM transformed data. For each dataset and for each pipeline,...
The P loadings, which are important to determine the trophic state, are expressed in mg P m−2day−1or g P m−2year−1. There are several methods to calculate these loadings (under nutrients in Fig.2). Waterborne P sources

was used to measure the importance values of each plant population in the community. The formula is as follows: IVi = (rfi + rdi +rdoi)/3 where IVi is the importance value of species i; rfi is the relative frequency of species i; rdi is the relative density of species i; and r...
Therefore, this model is used to calculate FVC in this study, and the formula is shown in Equation (1). FVC=(NDVI−NDVIsoil)NDVIveg−NDVIsoilFVC=(NDVI-NDVIsoil)NDVIveg-NDVIsoil (1) where NDVIsoilNDVIsoil is the NDVI value for the non-vegetated area; NDVIvegNDVIveg is the NDVI...
to calculate daily solar radiation for each stand by using the RayMan software [39]. The calculated solar radiation data were used with mean temperature, total precipitation, and relative humidity data to calculate potential evapotranspiration (PET) for each stand, as per Turc’s formula [31]. ...
